 * 2. The first of the values associated to the key is used in a regular
 *	expression to find some keywords corresponding to the language inside two
 *	environment variables.
 *	These values contains:
 *	- the "official" ISO language code and, if required, the dialect code
 *	  also ('bu' for Bulgarian, 'fr([-_][[:alpha:]]{2})?' for all French
 *	  dialects, 'zh[-_]tw' for Chinese traditional...), the dialect has to
 *	  be specified as first;
 *	- the '|' character (it means 'OR');
 *	- the full language name.
 * 3. The second values associated to the key is the name of the file to load
 *	without the 'inc.php' extension.
 * 4. The third values associated to the key is the language code as defined by
 *	the RFC1766.
 * 5. The fourth value is native name in html entities.
 *
 * Beware that the sorting order (first values associated to keys by
 * alphabetical reverse order in the array) is important: 'zh-tw' (chinese
 * traditional) must be detected before 'zh' (chinese simplified) for
 * example.
 *
 * When there are more than one charset for a language, we put the -utf-8
 * last because we need the default charset to be non-utf-8 to avoid
 * problems on MySQL < 4.1.x if AllowAnywhereRecoding is FALSE.
 *
 * For Russian, we put 1251 first, because MSIE does not accept 866
 * and users would not see anything.
